ADJUS'l'ABLE THIMBLEVFOR STOVE-PIPES.

SPECIFICATION forming part of Letters Patent No. 350.322, dated October5, 1886.

Application filed Iiiarch 9, 1886.

To all whom it may concern- Be it known that I, JOSEPH SALOIS, ofLawrence, in the county of Essex and State of Mas sachusetts,haveinvented certain new and useful Improvements in Adjustable Thimblesfor Stove-Pipes, of which the following is aspecification.

My invention is a stove-pipe thimble, and it consists in an improvedcontri'vance whereby such devices are rendered adjustable to suit theheight of the pipe or elbow portion of the pipe designed to enter thethimble, all'as hereinafterdescribed, and subsequently pointed out inthe claims.

It not infrequently happens in putting up stoves that the pipe availablefor use is unsuited in length to enter the thimble in the wall, andthere being no means at hand to reconstruct the pipe to meet theexigencies of the case, and no shop or store within ready reach at whichnew and suitable pipe can be obtained, very considerable inconvenienceis experienced, and eventually material expense incurred.

It is the object of my invention to provide improved means for obviatingthese difficulties and unnecessary expenses.

1n the drawings hereto annexed, and forming a part of thisspecification, Figure 1 is a front view of my thimble; and Fig. 2 isavertical section thereof on the line a m, Fig. 1, a portion of the wallin which the thimble is fixed being also shown in section in the latterfigure.

Similar letters of reference indicate corresponding parts in bothfigures.

A represents the frame or body of the thimble, of any suitablelengthsay, for instance,

three feet-and of a width sufficient to have the part containing thepipe-hole supported and adj ustably operated therein. This frame issecured in the Wall or chimney by being bricked or walled therein, andso far as it extends in the chimney practically forms a part thereof.

a is the front plate of the thimble, having the pipe-holeb formedtherein, as shown. This front plate is of considerably greater lengththan the frame of the thimble, and is constructed as a slide adapted tobe moved longitudinally in ways formed in the sidesof the Serial No.194,656. (No model.)

frame. The slide a has ratchet-teeth 0 formed in one of its sidesadjacent to the frame, and, a pawl, d, pivoted to the side of the frame,is'

adapted to engage said ratchet-teeth with its free end, and to be heldin engagement therewith by a spring, 6, also secured to the side of theframe and bearing with its free end on said pawl.

It will be noticed that the frame A is fitted in the wall so that itsouter face shall be flush, or substantially flush, with the face of thewall or chimney, by which arrangement the plastering and lathing orplastering portion of the .wall or chimney is brought between the outerney is obviated.

The form of the casing A to the rear of the slide a is such as to bemost suitable to lead into the chimney and'to hold the entirecontrivance in place therein, and at the same time constitute aperfectly spark and smoke tight conduit between the pipe-hole b and theinterior of the chimney. I have shown the portion mentioned as providedwith a flange, h, which serves as a' means for holding the framefirmlyin position,-though it is obvious that the frame might be given aform different from that shown, which would accomplish the same end.

The operation of my invention will now be readily understood. The framebeing bricked or otherwise secured in the wall or chimney at the pointwhere the ordinary thimble would have been placed, the slide a may bemoved up or down therein to bring the pipe-hole b to the position it isdesired to have it, and

there locked by means of the pawl d, engaging the ratchet-teeth 0, asclearly shown in Fig. 1.

The design of the front of the contrivance can easily be made such as toconstitute an onamentation,rather thanadisfigurement,ofthe wall, so thatno objection on this point can arise.

I do not confine myself or expect to be confined to the precise form andarrangement of parts shown, as these may be varied without departingfrom the spirit of the invention. The slide a may have more than onehole b, as shown, those not in use being closed by removable covers I).

What I claim is- 1. A stove-pipe thimble comprising a casing formed toact as a spark and smoke tight conduit between the outer surface of thewall or chimney and the interior of the same, said casing being providedwith a molding on the front thereof to rest in contact with thefaceplastering, and ways in the rear of said molding andface-plastering, and an adjustable slide movable in said ways andprovided with a hole for receiving the pipe, as and for the purposeshereinbefore set forth.
